There’s a chance of snow showers Saturday night, but the weekend forecast is generally pretty good. Transit riders will encounter extensive delays on Metrorail, and drivers will have their own problems on the Beltway in Virginia and on some D.C. streets.

The transit authority has a lot of maintenance to do on the aging Metrorail system, and "we're running out of weekends," said, Jim Hughes, one of Metro's top planners. We were standing on the mezzanine at Stadium-Armory Station, under a sign advising riders about upcoming track work that will disrupt service on the weekend of Nov. 5-7.

MARC train 538 on the Penn Line has been stopped south of New Carrollton for more than an hour, leaving passengers restless and wondering what's going on. MARC says a mechanical problem will delay the train by a total of 75 to 90 minutes; a rescue locomotive was dispatched to the scene around 6:30.
